eksoaatmisessa

Eksoaatmisessa is a Finnish term that translates to "in the exosphere" or "within the exosphere." The exosphere is the outermost layer of Earth's atmosphere, situated above the thermosphere. It is characterized by extremely low density, where atmospheric gases are so sparse that particles rarely collide with each other. These particles, primarily hydrogen and helium, can escape Earth's gravitational pull and travel into outer space. The exosphere gradually merges with the vacuum of space, and its upper boundary is not precisely defined. Its existence is crucial for understanding the interaction between Earth's atmosphere and interplanetary space, including phenomena like auroras and the behavior of satellites in orbit. Studying the exosphere helps scientists understand space weather and its potential impact on technology and Earth's magnetic field.
